# Converting data type of one variable to diffrent data type is called typecasting
>>> string = '123'
>>> type(string)

>>> integer = int(string) # Converting str() to int() data type.
>>> type(integer)

>>> float_number = float(integer) # Converting int() to float() data type.
>>> type(float_number)

>>> string, integer, float_number
('123', 123, 123.0) # str, int, float
